Abstract (en)
In a pad forming region electrically connecting an element forming region to the outside, in which a low dielectric constant insulating film is formed in association with in the element forming region, a Cu film serving as a via formed in the low dielectric constant insulating film in the pad forming region is disposed in higher density than that of a Cu film serving as a via in the element forming region. Hereby, when an internal stress occurs, the stress is prevented from disproportionately concentrating on the via, and deterioration of a function of a wiring caused thereby can be avoided.
